Benefits of technology

The present invention provides a sealing system that has the ability to quickly and accurately detect if sealing members are leaking. Additionally, it can prevent leakage accidents by identifying when sealing members need to be replaced. The system can also maximize the time of use of sealing members by accurately identifying the state of the sealing members.

Problems solved by technology

However, the mechanical seal type rotary sealing device has a complex structure, has difficulties in maintenance, includes a number of components, and requires a great manufacturing cost.
However, when compared to the mechanical seal type sealing device, the lip seal type rotary sealing device has a low durability, a low sealing performance, and a low safety, and thus is applicable to a narrower field.
In particular, in the field in which a rotary sealing device is used, a leakage accident leads to serious casualties and damage of property.

Abstract

One embodiment of the present invention relates to a sealing system having a leakage sensing function. A leakage sensing unit is arranged in a sealed space which is formed between sealing members of a sealing device body so as to sense, in real time, whether the sealing members are leaking, wherein a sensing value of the leakage sensing unit can be transmitted to the outside by using a communication unit.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This application is entitled to the benefit of and incorporates by reference subject matter disclosed in the International Patent Application No. PCT / KR2014 / 012879 filed on Dec. 26, 2014, Korean Patent Application No. 10-2014-0036056 filed on Mar. 27, 2014 and Korean Patent Application No. 10-2014-0179198 filed on Dec. 12, 2014.TECHNICAL FIELD[0002]Embodiments of the present invention relate to a sealing system for sealing a drive shaft that performs a rotary motion or a reciprocating rectilinear motion, and more particularly, to a sealing system having a leakage sensing function to quickly and accurately sense whether sealing members of the sealing system are leaking.BACKGROUND ART[0003]In general, a mechanism such as a gearbox, a chemical pump, a stirrer, a mixer, a reactor, a transmission, a drier, or a compressor includes a drive shaft, and a rotary sealing device is installed on the drive shaft to prevent a leakage along the drive sha...
